# Python Code Style & Documentation Consistent code style and clear documentation make codebases maintainable and collaborative. This skill covers modern Python tooling, naming conventions, and documentation standards. ## When to Use This Skill - Setting up linting and formatting for a new project - Writing or reviewing docstrings - Establishing team coding standards - Configuring ruff, mypy, or pyright - Reviewing code for style consistency - Creating project documentation ## Core Concepts ### 1. Automated Formatting Let tools handle formatting debates. Configure once, enforce automatically. ### 2. Consistent Naming Follow PEP 8 conventions with meaningful, descriptive names. ### 3. Documentation as Code Docstrings should be maintained alongside the code they describe. ### 4. Type Annotations Modern Python code should include type hints for all public APIs. ## Quick Start ```bash # Install modern tooling pip install ruff mypy # Configure in pyproject.toml [tool.ruff] line-length = 120 target-version = "py312" # Adjust based on your project's minimum Python version [tool.mypy] strict = true ``` ## Fundamental Patterns ### Pattern 1: Modern Python Tooling Use `ruff` as an all-in-one linter and formatter. It replaces flake8, isort, and black with a single fast tool. ```toml # pyproject.toml [tool.ruff] line-length = 120 target-version = "py312" # Adjust based on your project's minimum Python version [tool.ruff.lint] select = [ "E", # pycodestyle er...
